Hi all,
I'm having trouble with an IDL/HDF4 problem, and I was hoping someone
could point me at the correct solution. We are assigning attributes like
unitsCategory and scaleType to HDF dimension objects in our HDF4 files.
Not a big deal, in theory, since the HDF documentation from NCSA
discusses doing this.
However, I can't seem to find a way to do it in IDL. I can easily add
and read attributes to SDS objects using IDL, but the only
dimension-related routines seem to be HDF_SD_DIMGET, HDF_SD_DIMSET, and
HDF_SD_DIMGETID. The documentation for those routines indicates you can
ask for a count of the attributes on a dimension, but there is no
mention on how to set or read those attributes.
Does anyone know how to do this? Is there some undocumented way to get
to the HDF4 dimension attributes in IDL?
Thanks for any help you can provide,
Eric Winter
